The Stages Cycling officially endorsed Cannondale Si power meter allows you to transform any bike equipped with an alloy or carbon Cannondale Si chainset so you can train using power.

The first thing lot's of people ask when it comes to measuring power is; what does measuring power do? the answer is simple - power is a true metric that remains relatively unaffected by temperature, wind speed, road surface, road grade, time of day, heart rate or any other outside parameter that might affect a cyclist's performance.

Since power is the most consistent measure we have of a cyclist's effort, it's the best metric to use when tracking a cyclist's training. Power is the only measure that shows a true change in fitness or the performance of a cyclist over a period of time.

Power can also provide the most accurate gauge of real time performance, thus a power meter can serve as a rider's 'rev' limiter, ensuring that a rider puts forward their best performance and sustains it for the necessary time.

By training smarter with power you're guaranteed to get faster and able to put the hurt on your competition.

Stages Cycling is located in Boulder, Colorado and in 2010 their core product and engineering team banded together to pioneer power measurement for indoor cycling. It was the knowledge built through the engineering and manufacture of the team's proprietary indoor cycling bike that they then launched the outdoor power meter.

Over the last few years power-based training has been the main way to train for many Pro teams and as a result you will always see power meters on bikes during Pro races. Stages Cycling believe that power measurement is paramount to cyclists and triathletes training regimes, regardless of discipline. They believe that power-based training should be accessible to all enthusiastic cyclists, even those on a budget. Stages also believe that power meters should be simple, robust, and not force cyclists to make major concessions in terms of weight, aesthetic, or crank choice.

Stages Power meter offers the most advanced technology of any power meter currently on the market, yet is one of the easiest to install, maintain, and simple to use. With accurate readings and smart design the Stages Cycling Power Meter is the perfect choice for both amateur and Pro riders so you can guarantee that you are getting the most from your riding.
